Audio signal recording/reproducing apparatus for recording and reproducing high-definition television system audio signal of a plurality of channels

摘要

An audio signal recording and/or reproducing apparatus of a magnetic recording/reproducing apparatus for recording and reproducing audio signals and a video signal. An audio control signal converting circuit is responsive to a command for selecting an arbitrary one of audio signal modes of the 3-1 system, the 2-2 system and so on to convert an input audio control signal corresponding to the input audio signal mode into a recording audio control signal corresponding to the selected audio signal mode. An audio signal processing circuit converts the input audio signals into audio signals of the selected audio signal mode in accordance with the recording audio control signal. An identification signal generating circuit generates an identification signal including the recording audio control signal. The identification signal and the converted audio signals are recorded on the magnetic tape. Upon reproduction, the audio signals and the recording audio control signal indicating the mode of the audio signals are reproduced from the magnetic tape.
